Incidental Detection of Adrenal Myelolipoma: A Rare Case Report

Singh Harpa, Kundal Ramesh, Pooja Garg and Ninder Kumar

Adrenal myelolipoma is a rare, endocrinologically inactive neoplasm. It was initially described by Giercke in 1905, and 24 years later, Oberling coined the term ‘myelolipoma’[1]. Duckman and Freedman in 1957 presented the first symptomatic case treated surgically, and De Boils & De May reported the first case of radiologically diagnosed incidentaloma[2]. In the past, these lesions used to be primarily detected at autopsy. Recently, with widespread use of noninvasive imaging modalities such as ultrasonography, computed tomography and magnetic resonance imaging, incidental detection is more common, affecting men and women equally[3]. Accounting for 3–5% of all primary tumors of the adrenals, the true incidence of these tumors is not known, although it is thought to be 0.08%–0.4%, with increased incidence noted in the later decades of life[4].
